To all whom it may concem:

Be it known that I, LESTER A. SICHAEF'FER, a citizen of the UnitedStates, residing at Dayton, in the county of Montgomery and State ofOhio, have invented cer'- tain new and useful Improvements inCutting-Rollers for Cigar-Making Machines; and I do declare that thefollowing is a full, clear, and exact description of the invention7which will enable others skilled in the art to which it appertains tomake and usethe same.

My invention relates to machines for making cigars, and is a division ofmy application filed .I une l5, 1904, Serial No. 64,738.

In the accompanying drawings Figure 1 is a sectional elevation of themachine on a line corresponding substantially to B, B, Fig. 4. Fig. 2 isa sectional eleva-` tion showing the cutter roller and arm in normal orwaiting position. Fig.A 3 is a plan View of the wrapper cutter arm anddie-plate with the said arm`at the second arc of the said plate. Fig. 4is a plan view of the cutter arm and die-plate, showing the rolleractuating mechanism on said arm as about to be released for the actionof the spring and with the roller in position to I turn on the arcbeneath to normal position. Fig. 5 is an enlarged diagrammatic view ofthe die-plate, Showing the cutting roller atthe right in full lines inits normal position, and at the left in dotted lines at the beginning ofits rotary movement, and again at the right in dotted lines in positioncorrespondingsubstantially to Fig. 4.

The mechanism thus shown has to do principally with the roll for cuttingthe wrapper andmeans for carrying and operating the roll. Specificallysaid means or mechanism includes a roll supported on a vertical axis andadapted to be rotated on said axis to run around upon the edge of thedie or wrapper cutter and sever the wrapper from the leaf as it goes. Inthis operation the roller runs to the left along the front or outer sideor edge of the die, and back along the inner side cutting as it goes,and it is turned on its axis at the end of the die sufficiently totravel forward with the same front along the inner portion of the die asit maintained along the outer portion thereof.

The turning position of the roller is clearly disclosed in Fig. 3, andthis turning is mechanicallyeffected when the swinging arm carrying theroller has reached the end of its outward sweep. As thus shown Hrepresents the roller carrying arm, which is pivoted on the main frameor table of the machine in bracket H and has the cutting roller hmounted in the outer free end thereof. The said roller is journaled inbracket h on spindle. h2 supported in a vertical socket h3 in the armI'I. A coiled or spiral spring h4 about the upper and reduced portion ofspindle h2 in socket h3 is adapted to exert a constant downward pressureon the roller while at work, and serves to give the roller a firm butyielding l pressure. A crank or arm h5 is fixed on the upper end of'spindle h2 above arm H with which connections are made for rotating theroller axially so as to follow the die or cutting edge c around fromstart to finish. y At this point I may explain that I find very materialadvantage following around the edge of the die with the cutter rollerand cutting at only a single point in the travel rather than cuttingbroadly across the die at one sweep of the roller and going back idle,for the reason, rst, that by cutting with the whole roller at a timethere is great danger of defective cutting at some point, here or there,and which leaves the wrapper unsevered from the leaf at such point. Thisis especially liable to occur at the ends of the die where the edgesdull most easily, and sometimes it occurs more or less along the sidesas well. But by running the roller around the circuit of the die I cutat only one point as I go and both avoid the objection of dulling someone or other 'prevented from proceeding until the wrapper is otherwiserelieved. Furthermore, I get essentially a shearing cut all the wayaround by reason of the irregular curved outlines of the die and thedifferent arc movement of the roller in respect to the die, so that Inever fail to sever the wrapper all around and in no less time than theother way. Now, in doing this work, roller h adapts itself to the edgeof the die and` switches around at both arcs, x and y, and cuts herealso as it goes. Normally, said roller is entirely clear of thedieplate, Fig. 2, andthe space above said plate is otherwiseunobstructed to allow said plate to be raised.

, But when lever H is carried to the left the roller first strikes thearc x, Fig. 5, and travels over the near edge of the die to the otherarc y. Once there its spindle is axially and automatically reversed halfway, which causes the roller to travel back on the inner side of thedie, as it has done in dotted lines at the right in Fig. 5. From thislatter point it turns to the intersection of its original position onarc x and at the same time is automatically reversed to startingposition, full lines. The mechanism for effecting these operations ismostly carried by lever H, and consists of a reversing or switchingcrank h6, rod k7 connecting crank h6 with crank h5. Spring hs islikewise connected to crank h5, and at its other end to cam hm which isrigidly attached on Crank hG inward from its pivot h5 on lever H. Crankh6 has a cam g directly off its pivot to the rear adapted to be engagedby a fixed projection g on stationary arm H2, as reversal of roller h isto be made and as shown as partially turned in Fig. 3. Once at thispoint a further push of lever H to the left throws crank h5 by means ofprojections g past its center and brings it under the pull of spring hsto complete the reversal. Then the Patented July 16, 1907'.`

parts instantly assume position as in Fig. 4, and the reversing actionof spring h8 is temporarily suspended by spring pressed headed bolt g2engaging at its upper point in a hole in cam h1", thus for the timeconnecting said parts rigidly, as in Fig. l.

Upon returning lever H to normal position an arm g3, with a beveled edgeand operating as a cam enters over the langed head oi bolt g2 anddepresses it suciently to disengage its top point from cam hw, thusliberating the parts again to the pull o springhg. As this disengagementoccurs the roller h has reached the reversing point ot the arc oi thewrapper cutting die, and spring h8 instantaneously reverses roller hthrough its operating and associated parts ba ck to nor- Inal position.

Incident to the last reverse action of roller h by spring h8 there issuch impetus given to the roller that it at once assumes its rightworking position, but spring h8 would carry it back out of this positionmore or less if not prevented. To this end I employ a spring pressedbolt g, Fig. l. Normally said bolt is up, and is only depressed whencrank h5 rides over it, said crank being beveled on one side to do so.Bolt g4 is acting as a back stop in Fig. l and always when the parts arenormal.

Roller h is in initial but opposite reversing positions in both Figs. 3and 4, and a corresponding position to Fig. 4 is shown in dotted linesFig. 5, and the reversal thereof and the other details of its operationwill be understood from the description already given. Assuming now thatlever II is normal, roller h rst assumes position as to the die as it ismoved up to full lines, Fig. 5, and then travels around upon the edge ofthe die and reverses upon its arcs as already described and with theoperating parts relatively as seen in Figs. 3 and 4, just before eachreversal occurs.

It is to be observed that the circle of the die is the path the cuttingroller describes in its complete movement or trip, and that said rollersweeps its outer end around at the points x and y at what are regardedas the ends of the die so as to keep the outer end out all the time. Inno case does the roller overreach both edges of the die at the sametime, and the peculiar shape of bracket h contributes to'this result.Thus,

it is noticed that said bracket is of a crank or L pattern or shape,having the spindle or shaft h2 connected with the end of its horizontalarm, and the shaft for roller h engaged through the end oi its verticalarm. This brings spindle h2 over one end of roller -h, and it maintainsthis relation to the roller as the roller travels its circuit over theedge of die c, as seen in dotted lines Fig. 5.

What I claim is 1. In a machine for making cigars, a pivoted arm adaptedto swing horizontally back and forth within fixed limits, a cuttingroller mounted thereon and means to cause said roller to travel on twodifferent arcs of a circuit with the arm pivot at the center of itsmovement, in combination with a die plate having a continuous andirregular curved cutting edge disposed obliquely to the travel of saidroller to provide a shearingcut.

2. In a machine for making cigars, a die with circular ends, incombination with a pivoted arm, a roller on said arm and means toreverse said roller at the ends of said die comprising a spindle andcrank for said roller, a switching crank and lever connecting the samewith said roller crank, a spring pressed bolt and springs for saidparts, and stationary projections adapted to engage said switching crankand said bolt.

3. In a machine for making cigars, a horizontally mov able arm, a cutterroller and a bracket supporting the roller having a vertical shaft insaid arm, and means connected with the top of said shaft to turn thesame conrprising a pair of connected levers and a stationary part toactuate said levers.

4. In a machine for making cigars, an arm, a cutter roller thereon and avertical shaft in said arm supporting,r said roller, in combination witha switching crank having a cam, connections from said crank to saidshaft, and meansto engage said cam and rotate said shai't, whereby saidroller is horizontally rotated.

5. In a machine for making cigars, a horizontally rotatable arm, aroller and a bracket carrying the roller having a crank spindlerotatable in said arm, in combinat-ion with mechanism to rotatesaid-spindle comprising a connecting lever and a reversible crank and aspring therefor, and stationary means adapted to engage said reversingcrank during the movement of said arm.

In testimony whereof I sign this specification in the presence of twowitnesses.
